The rbl wrapper

A recent addition to the rblcheck package is the rbl shell script, which is a simple wrapper around rblcheck, with one special feature: it will read a global rblcheckrc (usually in /etc or /usr/etc), and then a .rblcheckrc from the current user's home directory. These files can contain any of the usual rblcheck command-line arguments (see the Section called rblcheck basics), but are most useful for setting the most common RBL-style listings you use day-to-day.

For example, your personal .rblcheckrc might contain:

-t
-m
-c
-s relays.ordb.org
-s relays.visi.com
-s some.future.rbl.listing

Please note that for mail filtering, or any performance-sensitive use, you should use rblcheck directly, to avoid adding additional latency to the process. rbl is mainly intended as a convenience tool for interactive use.
